It's because I'm me, 
not just one of the sisters.
Nicht irgendeine von uns Schwestern,
sondern genau mich.
Y es porque soy yo,
no una de las quintillizas.
Y es porque soy yo,
no una de las quintillizas.
Moi et rien que moi,
pas une de mes sœurs !
Perché sono io,
non semplicemente una delle sorelle.
É porque eu sou eu,
não apenas uma das irmãs.
Потому что я это я, а не одна из сестёр!
